MACHIINE FOR PACKINGMEATp sriicIFIcA rIoNrormin part of Letters Patent No. 223,522,:dated January 13 18 80.

Application filed December 19, 1379. i i t i l Chicago, in the county of Cook and State of Illinois, have invented a new and useful Machine for Packing Meat in Cans, of which the following is a specification.

Heretofore, so far as I am aware, machines for this purpose have been liable to the objectlon that the air, having no certainmeans of escape from the can, would frequently rupture it, or should the can not break, the air would remain in it, forming a bulge, and the meat would be liable to spoil.

, Another objection to these machines is, that the outsides of the cans become covered with thejuices of the meatand small particles of meat, causing waste and necessitating the cleaning of the cans after they have been sealed. The amount of work done within a given time by these machines has also been small in comparison with that done by my improved machine, and they required a greater number of attendants.

The general object of my invention is to overcome the objections above mentioned.

The object of the first part of my invention is to insure the escape of the air from the can and to prevent the meat and its juices from collecting on the outside of the can to which end my-invention consists in packing the meat in the can from the bottom, about its middle, upward. i

The object of the next part of my invention is to compress and pack the meat into the can to which end my invention consists in combining a can-holder, a meat-receptacle, plunger and plunger-"rod, and theiractuating-cams.

The object of the next part of my invention is to insure all the meat in the receptacle being forced into the can; to which end my i11- vention consists incombining a meat-receptacle having a concave bottom on the inside and a downwardly-projecting nozzle with a plunger having a convex bottom on the outside and a plunger-rod. y

The object of the next part of my invention is to hold the can firmly while the nozzle of the meat-receptacle enters the can-opening; to which end my invention donsists in provid ing a holding-plate upon the main frame, which securely holds the can until thenozzle has entered its opening. i y

The object of the neXtpart of my invention is to eject the cans, when filled, from the machine; to which end my invention consists in combining a can-holder, a meat-receptacle, plunger and plunger-rod, and their cams,and a cairejecting lever and its cam. l

The object of the next part of my inven is to introduce the cans into the machine and tion I end my invention consists in combining a can-feeding belt, a can-holder, aplate for holding the can in the holder, a meat-receptacle, plunger, plungenrod, and ejecting-lever, and their cams, and a beltfor carrying away the filled cans.

The object of the next partof my invention is to arrange a series of can-packers so that they will only requirefone attendant to feed them; to which end my invention consists in combining a stationary frame, a revolving frame, a series of can-holders, and a series of nieatreceptacles, plungers, and plunger-rods, and their actuating-cams. I

The object of the next part of my invention is to so construct the machine as to have the revolving frame carrying a series of can-packers move smoothly without jerks or jar and at a moderate rate of speed, so as to compress the meat progressively in contradistinction to a sudden impact, and thus allow the air to escape; to which end my invention consists in combining a stationary frame, aframe secured upon and revolving with a spindle having its hearings in thestationary frame, a series of can-holders, meat-receptacles,*plungers, and

plunger-rods mounted upon the revolving frame, and their cams, a gear upon theend of the spindle, and a worm for driving it.

The object of the next part ofm'y invention is to prevent the meat in the receptacle from chilling, which would have a tendency to cause it to cake and clog the machine; to

In the accompanying drawings, which illusa to convey them away when filled; to which i i which end my invention consists in combining gg trate my invention embodied in a machine in the form now best known to me, Figure 1 is a plan or top view. Fig. 2 is a side elevation. Figs. 3, 4,5, 6, 7, S, 9, and 10 are detail views, showing the meatreceptacle, plunger, and 1:)lun'ger-rod in the different positions during the operation of filling a can; and Figs. 11 and 12 are detail views, showing the steam-pipefor keeping the meat-receptacle warm.

-Up0n the'bed-plate A of' the machine is bolted an upright circular skeleton-frame, B. Another skeleton-frame, 0, having a circular base, 0, revolves within the frame B, being secured upon an upright shaft or spindle, D, having its hearings in the top and bottom of the frame B. A gear-wheel, E, is secured upon the lower end of this spindle beneath the frame B, and is driven by a worm, f, on a horizontal shaft, F, which is driven in any well-known way.

It will thus be seen that the frameOrevolves within and independently of the frame B.

A can-holder, c. is secured upon the circular base 0 of the frame 0, between the uprights c of the frame. Immediately above this holder, and working loosely on the uprights c.is a tubular meat-receptacle,G, the general shape of the bottom of which is concave. At the bottom of this receptacle is a down wardlyprojecting tube or nozzle, g, which communi cates with its interior, and upon its outer side is a pin, g, which works in a circular cam-rail, on the frame 13. This cam gives the required movement to the meat-receptacle, hereinafter fully to be described, and may be re cured to the frame B by set-screws, so as to be capable of adjustment, if desired.

Immediately above the meatreceptacle, and also working loosely 011 the uprights of the frame 0, is a hollow tubular plunger, H, the

bottom of which is convex upon its exterior, and is provided with a central circular aper' ture, h. The movements of this plunger are controlled similarly to the meat-receptacle by a pin, h, working in a circular cammail, h also secured to the frame B. This hollow plunger has on its inner side a vertical slot, h.

From this slot projects a pin, t, upon a plungerrod, l, which works loosely vertically in thehollow plunger. The end of the plunger-rod 1' accurately fits and works in the circular aperture h and in the tube or nozzle of the meat-receptacle. The movements of this plunger are controlled by a cam, K, secured upon the top cross-bars of the frame B and projecting downwardly within the frame 0 around the upright spindle D. A down-hanging cam, 7c, projects from the cam K at a proper point, and accomplishes the ejectionof the filled cans, as will hereinafter be set forth, by means ofa swinging lever, L, pivoted upon an upright, i, in rear of the can-holder, and working in guides l 6 upon each side of the vertical slot- Z in'the can-holder.

The empty cans are carried into the canholder by means of an endless belt, M, working over pulleys m m, and receiving motion through a crossed belt from the worm-shaft on the opposite side of the machine, and the ejected filled cans are'conveyed from the machine by another belt, N, working over .pulleys an, and also receiving its motion from the worm-shaft, but by means of a band, in an opposite direction from that of the belt N.

The circular openings 0 in the cans 0 are made a little larger in diameter than the nozzle on the end of the meat-receptacle.

In order to keep the meat-receptaclewarm, so as to prevent the meat from chilling, which would have a tendency to clog the machine, any suitable apparatus maybe used. I prefer, however, to employ a steam-pipe, Q, coiled, as shown, against or in close proximity to ,the receptacle, and supported upon bars R, depending from the interior of, the cam K.

By using a steain-pipe in this manner the temperature can readily be controlled by means of an ordinary steam-cock.

The operation of the machine is as follows: A can is carried by the t'eeding-a 'iron into the holder as the interior frame revolves. A plate, P, secured upon one of the uprights of -the frame B, forces the can into its place in the holder and holds it in place while the meatreceptacle descends, its nozzle entering for some distance the opening in the can. The attendant now deposits a given weight of meat into the receptacle. As the frame continues-to revolve, the tubular plunger and its contained plunger-nod descend together at a uniform speed into the meat-receptacle and force some of the meat through the nozzle into the can. The operation just here, and subsequently until the can is filled, is this: The meat is deposited first on the bottom of the can, about the center, and spreads around and upward, thus filling the can from the bottom upward, while the air is free to escape through the opening between the can and nozzle. As the frame continues its revolution the tubular plunger ceases to descend and remains for a time at the same level, while the plunger-rod descends through the meat-receptacle and through and beyond the nozzle, forcing more of the meat into the can and compressing it. The plunger-rod now rises until it is about flush with the bottom of the tubular plunger, the plunger and meat-receptacle remaining at the same levels. The meat-receptacle now rises,'not sufficiently, however, to lift the nozzle out of the can, and at the same moment the tubular plunger and its contained plungerrod descend, thus forcing the remainder of the meat; in the receptacle into the nozzle. The meat-receptacle and tubular plunger now remain at the same levels, while the plungerrod descends into the can, forcing the last of the meat into it. The receptacle, tubular plunger, and plunger-rod all now rise, and the can is ejected from the holder by the pivoted lever on to the apron, which carries it away.

As soonas the meat in the can is relieved from the final pressure of the plunger-rod it 223,522 r r s expands about flush with the can-opening, so

that no air will remain in the can when sealed. The exact degree of pressure necessary to accomplish this result can be regulated bythe cam which Works the plunger-rodL q I have described and shown but four pack! ing apparatus; but in practice as many as ten or more areused in one machine, all the parts being worked by one set of cams. y

By thus causing the machine torevolve it is only necessary to employ one attendant, who

can readily ,feed the meat to ten or morere ceptacles as they come round.

Instead of having the framecarrying the packers revolve, it might remain stationary and theframe carrying; the cams bemade to revolve, or the packers might be arranged in l a straight line and the cam-bars be madeto. reciprocate above them.

other modifications will present themselves to persons skilled in the art without departing from the spirit of my invention.
